09:22 AM veverak: fml
09:22 AM veverak: solder shortcuted two cpu legs (SDA and SCL of I2C...)
09:23 AM veverak: well, thing is, the solder was behind the legs almost under the the STM32 itself
09:23 AM veverak: funny thing to try to lift two legs on this CPU and access the space behind them
09:23 AM veverak: funny thing
09:35 AM rue_mohr: ouch
09:36 AM rue_mohr: wouldn't it be a thing to do a dummy mockup assembly on paper
09:37 AM rue_mohr: but wouldn't show ya missing signlas
09:38 AM veverak: that was not the problem here
09:38 AM veverak: I am pretty sure I put too much solder in that place before
09:38 AM veverak: and there are two lines going under the CPU

01:22 PM veverak: tried
01:22 PM veverak: Tom_L: I noticed that I can't really heat the solder near the CPU itself
01:22 PM veverak: only at the legs
01:22 PM veverak: and didn't want to overheat it
07:00 PM rue_mohr: smoked my elbow on the corner of a 1/2" steel plate today
07:00 PM rue_mohr: that'll hurt for a while
07:00 PM rue_mohr: but I didn't drop my screwdriver down the elevator shaft!
07:16 PM Tom_L: no warning "HOT" on it ehh?
10:11 PM rue_mohr: hah
10:11 PM rue_mohr: it was a corner behind me, pulled my hand back and elbow met the corer of the place
